Application filed July S, 1912. Serial No. 708,152.

To all whom it may concern:

Be it known that I, WILLIA F. JACOBS, a citizen of the United States, and a resident of Ottawa, in the county of La Salle and State of Illinois, have invented certain new and useful Improvements in Hay-Carriers; and I do hereby declarethat the following is a full, clear, and exact description thereof, reference being had to the accompanylng drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates-to improvements 1n hay carriers of that kind known as crossdraft hay carriers, wherein the hay sling is suspended from an overhead track and is raised or lowered in loading or unloading and is transported from one place to another by. the movement of. the carrier along the track. i

The invention relates particularly to an improvedlocking mechanism by means of which thedraft rope may be: clamped or held from movement or released in any position of the load.

The invention consists in the matters hereinafter described and more particularly.

pointed out in the appended claims.

In the drawingsFigure 1 is a view in side elevation, showing the carrier mounted upon a track; Fig. 2 is a view in front elevation of the hay carrier with the hay sling supporting pulleys removed; Fig. 3 is an enlarged cross-sectional view taken on line 33 of Fig. 2: Fig. 4 is a cross-sectional view taken on line 4 4 of Fig. 3; Fig. 5 is an enlarged orbss-sectional View taken on line 55 of Fig. 1; Fig. 6 is an enlarged cross-sectional view taken on line 6-6 of Fig.1. y r

Referring to the drawings, an overhead track A, provided with laterally extending tread flanges a, a (Fig. 1), supports the hay carrier. The frame of the carrier proper comprises, as'its main parts,a truck Band a supporting frameG attached to and depending from said truckB. The truck comprises two truck frame members B rigidly connected together by means of horizontal, transverse, stay-bolts 6. Both ends of-each of said truck frame members B terminate in upwardly extending arms (Fig. 2) with which are pivotally co'nnected the wheel bearing members E the latter being provided at their extremities with wheels a mounted oninwardly extending axles. The stay-bolts Z), 6 are provided with eyes Z), 6

to which are attached ropes b 12 by which the carrier may be pulled along the track. Said truck frame members are also provided with outwardly extending horizontal lugs b to which are bolted parallel vertically arranged side frame members C of the supporting frame C. Said side frame members 1 C are rigidly held in parallel relation and at a distance from each other by stay-bolts extending through said side frame members "at convenient points. Between said side frame members C is located a large pulley or rope sheave D 3) supported through the medium of roller bearings 03 upon an axle cl. Said axleextends through said side frame members C and its extremities are loosely confined in segmental bearing plates E (Fig. 1). Said bearing plates B have curved bearing edges correspending with the quadrants of concentric circles and are adapted to engage and slide endwise in slots in the side frames C, said slots being of similar shape butv of larger arc, thus permitting the pulley or sheave D to have a limited swinging or oscillatory movement, through an arc corresponding with the extent of travel of said bearing plates E within the slots E. Integral with said bearing plates E are arms F (Figs. 3 and 4t) said arms being located at the inner surfaces of the side frames C and pivoted bolt 9 is a bell-crank lever G, the same hav-- ing a horizontally extending longer arm G and two shorter arms G extending upward *from the pivot bolt 9. Said shorter arms "G are parallel and are adapted to engage the rounded end of the finger F by means of semi-circular slots at the extremities of said arms. With the extremity of the longer arm G of the rocking lever G is pivotally connected the frame of a smaller sheave H, which depends from said arm. Pivotally mounted between the shorter arms G of the lever. G, by a pivot bolt 2', adjacent to the extremities thereof, is a U-shaped link mem her I, extending horizontally outward from said pivot bolt. A second U-shaped link member J is mounted on a pivot j, between the side frames C at the upper portions of the same, said link member extending down ward from said pivot j. Said link members I and J are loosely connected by means of a pivot pin 2' 011 which is also mounted, between the legs of the U'-shaped link members, a movable jaw member K preferably having its inner surface grooved transversely of its length. A fixed jaw member K is rigidly mounted between the side frames C inside of and generally parallel with the movable j aw member Said stationary jaw member is also provided 'with a grooved gripping surface facing the like surface of the movable jaw member K. Near the outer'extremity of the longer arm G of the rocking lever a U-shaped link L is pivotally connected at its lower end, with said lever. Said link L engages at its upper enda hook M which is attached to and preferably made integral with a rock shaft M Saidrock shafts extends between the side frames G and has bearing at its ends in i the latter. One extremity of said rock shaft M extends beyond one of the side frames, and to the projecting end of said rock sha ft is'rigidly secured a lever N, to the outer end of which is connected a trip operating rope N Midway of the length of thelonger arm G of 'the bell-crank lever G, two semispherical depressions 9 (Fig. 6 are formed in said arm, thejsaine being located on opposite sides of said "arm. 'Said depressions are' adapted to receive steel ball plungers 0 (Fig. held within casings P, P tlittBX- renalaterally rrpm the side frames fC Said ball plungers 'O, O are constantly forced toward the lever arm G by means of expansively acting, coiled springs O 0 set screws P P are inserted through the outer ends of the casings P, and hear at their inner ends against the springs O}. means of said set screwsthe tension off said springs may be regulated. Lock nuts P P are "provided to hold said set screws in desired position. The function of the ball plungers is to yieldinglyhold the bell crank leverG in its'normal position or with its horizontal 'arm elevated and the clamping jaws disengaged from the draft rope,

and they act to prevent undesired movement of said lever underthe weight offthe slingsand sheaves S, S, or otherwise than by the weight of the load. Guide pulleys RQR" (Figs. 1 and 3) are mounted between the'side frames C 'at the lower and lateral extremities of the frame C; the guide pul ley B "being located between the gripping K and IQ and the guidepulleyR above the sheave H J The sheavesS are provided with pulley wheels, adapted to be lis' ecl 'V t ql fe 7 1 an w h its downwardly extenditfg armss", etermin'ating round the hay or like material be 'ele-r vated or carried. W 1 1 Thedraft rope T is permanently attached -to the pulley S, by means ofa metal head .V which.isprovided with arms Yfl'a dapted to straddle the sheave S and to be attached tofthe extremities 'of the pulley axle. The.

draft rope T extending upward from the metal head Vtake's thf following direction; it first passesftliroufgha "engages the pillljey o'ffthe "sheave I-I t enje'xtends down ward through the sheaves S and ST, then up over the,fgiiideypiilley B,between the jaws K and K; then .iartiun'd the upper atriarc large sh'eave D, "then downward over th efguide faiid thence to the place which powerjis applied thereto for From the above d "sc'ripnan of the construction of the device, the operatibn of the sgnne 'willbe readily understood. A'ssumthat the in'e 1nbe are in the-position shownin Fig. 1, a 'that-"a'quantit'y of hay is about to be liftedihnd transported; the

A le s. a th force is exerted the rope "will pass freely over the pulleys because the large sheave D at this time fthe entrenie position to which it is carried njthe'direction of the the limit of its-swinging movement; in 'jthe @l ree n 0 h aft. Q he r rfe it e inst'aiit the lifting [force 'cealses, the weight of the load is transferred from the sheave D "t'o the sheav H. The action of the weight ir'hinhdiately hvercomes the r-e i mae 'fsr tlie ball plungers the' arm (j? of the 'bn-eatn'kf Gr drops downward a short distance.

In case the load is removed when the carrier is in its locked con dition, a pull or erk on the draft rope will unlock the rope; it being evident that the main sheave will be thereby carried back to its original position, which movement will operate the links controlling the locking jaws.

An apparatus embodying my invention may be variously modified with respect to its details of construction without departure from the spirit of the invention, and I do not, therefore, desire to be limited to any of the particular features of construction illustrated in the accompanying drawings and hereinbefore described, except as pointed out in the appended claims.
